Sentences Containing 'calorific'
The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it.
The quantity known as higher heating value (HHV) (or "gross energy" or "upper heating value" or "gross calorific value" (GCV) or "higher calorific value" (HCV)) is determined by bringing all the products of combustion back to the original pre-combustion temperature, and in particular condensing any vapor produced.
The quantity known as lower heating value (LHV) ("net calorific value" (NCV) or "lower calorific value" (LCV)) is determined by subtracting the heat of vaporization of the water vapor from the higher heating value.
LHV calculations assume that the water component of a combustion process is in vapor state at the end of combustion, as opposed to the higher heating value (HHV) (a.k.a. "gross calorific value" or "gross CV") which assumes that all of the water in a combustion process is in a liquid state after a combustion process.
